Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90112, here are decompositions:

5 + 90107 = 90112
23 + 90089 = 90112
41 + 90071 = 90112
53 + 90059 = 90112
59 + 90053 = 90112
89 + 90023 = 90112
101 + 90011 = 90112
149 + 89963 = 90112

Showing the first eight; more decompositions exist.
